Additional Information

• As of the 3.5 Sensor, command line signature updates no longer require RepCLI Authentication and can be run as a script or scheduled task.
• Virus Definition Files are required only when "On-access file scan mode" is set to Normal or Aggressive.
• If the "Allow signature updates" Policy setting is Disabled, signature updates via RepCLI will fail.
